BENDING FORCE: the physical nature of some products make them more suitable for testing via a bending test.

Generally the higher the force to bend (usually up to the point of break) the firmer the sample.

The force and distance references at the point of break provide a measure of BREAK STRENGTH by this action.STIFFNESS is associated with a material that cannot easily be bent and therefore has a high degree of hardness and usually lacks flexibility.FLEXIBILITY is the opposite of this and is a characteristic of a product that can be bent, flexed or deformed to a much higher degree of deformation before failing.

Why
bother to floss? Periodontal disease is
one of the most prevalent degenerative conditions in this country, afflicting
adults beginning in their late 20's.

It is the disease that causes people to
lose their teeth by slowly dissolving the supporting bone structure surrounding
teeth. The most common symptoms of the disease are bad breath and bleeding gums.

Flossing is a simple
oral hygiene procedure that, when performed daily, can ensure healthy gums and
teeth that last a lifetime. Experts say it's as indispensable to a healthy
mouth as brushing, yet most people find it uncomfortable and don't do it
regularly. Modern dentistry and dental products have begun to address the
problem of plaque buildup which causes periodontal disease.
